LOS ANGELES, Ca. (KTLA/CNN) - A grandmother was killed, and her infant grandchild was hurt, when a female driver lost control of her car while backing out of a driveway in Anaheim and hit them, police said.

The crash happened on Nutwood Avenue about 2 p.m. when the woman hit Norma Revolorio, 44, who was walking on the sidewalk with her two grandchildren, one who was an infant in a stroller, the Anaheim Police Department told KTLA.

"I saw a baby in the street with a stroller on top of it, and so I yelled for my granddaughter to call 911 there's a baby in the street," Angie Jared, who lives close to the crash site, told KTLA. "I didn't see the person under the car until a few minutes later when I went back out and I saw a foot protruding from the front of the car, underneath the front of the car."

Jared said a neighbor ran to get his car jack in hopes of helping get Revolorio out of underneath the car, but by that time first responders were on scene.

Revolorio, a resident of Anaheim, was taken to a hospital in extremely critical condition. She later succumbed to her injuries, police confirmed.

The injured child, who police described as a baby girl between the ages of 1 and 2, was taken to a hospital and is expected to survive.

The second child, an 8-year-old, was not injured, police said.

Nutwood Avenue, between Ball Road and Beacon Street, was closed temporarily but it was reopened just before 5 p.m.

The driver was on scene and cooperating with police.

As of 6 p.m. she had not been cited or released, police said.

Investigators were trying to determine what contributing factors were involved in the crash.

Scott Heatherly, 50, of Arnold, is charged with second-degree assault and first and second-degree property damage. Arnold Police say the charges stem from an assault which appears to have been brought on by road rage Friday night and was caught on surveillance camera.
